Yeah, I did that online assessment about a month ago, and I'm still waiting for a job lol, prob because most jobs have been taken for the Xmas holidays. They send u the results straight away, with graphs comparing you to all the people workin in Coles Myer
It's not that hard, just takes a long time. There are LOTS of questions, took about an hour I think? If I remember right...the test is divided into two, the first bit is the one where you have to think. It has some easy math questions, lots of picture questions where they give u 6 pictures and u have to say which 2 don't belong with the others. And there are english questions, they give you 6 words and you say which doesn't belong with the others.
The second bit is about 80 questions, all beginning with "Which would u rather do": a) work in a lab analysing whatever or b) work outdoors planting trees. One of the questions is would you rather sharpen knives or file receipts! So it's not really a test, just figuring out where u would be most suited to work
Oh yeah, don't worry if u don't finish all the questions in the first bit, it says it is very rare for somebody to do that (trust me, there are heaps). Good luck
